2. Select the QoS queuing method.

•

Change the queuing method to strict priority (SP).

device(config)# qos mechanism strict

bandwidth scheduling mechanism: strict priority

Qos profile bandwidth percentages are ignored

•

Change the queuing method to mixed SP and WRR.

device(config)# qos mechanism mixed-sp-wrr

bandwidth scheduling mechanism: mixed weighted priority with strict priority

Unicast Traffic

Profile qosp7 : Priority7(Highest) Set as strict priority

Profile qosp6 : Priority6 Set as strict priority

Profile qosp5 : Priority5 bandwidth requested 25% calculated 25%

Profile qosp4 : Priority4 bandwidth requested 15% calculated 15%

Profile qosp3 : Priority3 bandwidth requested 15% calculated 15%

Profile qosp2 : Priority2 bandwidth requested 15% calculated 15%

Profile qosp1 : Priority1 bandwidth requested 15% calculated 15%

Profile qosp0 : Priority0(Lowest) bandwidth requested 15% calculated 15%

Multicast Traffic

Profile qosp7 : Priority7(Highest) Set as strict priority

Profile qosp6 : Priority6 Set as strict priority

Profile qosp5 : Priority5 bandwidth requested 25%

calculated 25%

Profile qosp4 : Priority4 bandwidth requested 15%

calculated 15%

Profile qosp3 : Priority3 bandwidth requested 15%

calculated 15%

Profile qosp2 : Priority2 bandwidth requested 15%

calculated 15%

Profile qosp1 : Priority1 bandwidth requested 15%

calculated 15%

Profile qosp0 : Priority0(Lowest) bandwidth requested 15%

Observe that the verification step is not necessary with either of these choices.

3. Return to privileged EXEC mode.
